I forgot about that! 7x42 is covered. I'd like to try to the 8x42 EDG also, currently the SF in filling that niche, I still like them too much to sell them, like your UV's.
The 8x56 SLC will definitely take care of 8x in a big way, I'd love to try one of those. Huge glass and exit pupil, would be like watching everything on a big-screen TV.
I've been getting into old porros and I compared my 7x35E's to the 7x42 EDG and I must say I barely saw a difference in the depth/stereoscopic thing. It's not a huge thing to me, they both have nice depth of field. I was expecting the 3D feel in the porros to be stronger, it was there but barely visible to my eyes. I just received a gorgeous pair of the 12x40E this morning and the 3D feel is stronger - maybe because of higher power? Or bigger objectives?
Scott,
I have had both the 7x35 E and 12x40 E. I liked the 7x Es optics (though I would have preferrred the FMC version but they are hard to find), but I found the apparent field of view too confined (~51*, I think Henry measured it at 53*?, still rather narrowish). But I would think the 7x would offer a more 3-D view since the 3-D effect goes down as you go up in magnification. Focus speed also affects your peception of depth. I used the 12x40 for stargazing. I think the FOV was 5.5*? That would make the rough AFOV around 66*, much more "open" than the 7x35 E
Perhaps the difference you're expirencing btwn the 7x and 12x Es is the difference in apparent field of view, which is greater in the 12x E (mulitply the magnification by the TFOV). Pincushion and AMD also affect the apparent FOV but the simple formula gives you a general idea.
As to the 8x56 SLC giving you the feeling of watching everything on a big screen TV-- it probably won't. The TV screen is often used as an analogy for apparent field of view. The 8x56 SLC has around a 61* AFOV. That's a wide but not extra wide like the 8x30 and 10x35 E2s, which have a 70* AFOV--more akin to that big screen TV.
The larger exit pupil in the 8x56, 7mm, is only useful in the dark or near dark when your pupils open all the way, and that's assuming that your young enough that your pupils can open to 7mm. The last time I measured my fully opened pupil it was 5mm and that was at my eye doctor's office about 10 years ago. It's not part of my bi-yearly exam, I asked his assistant to measure it when I was getting my eyes tested. It's probably smaller now.
During the day, your pupils would be stopped down, so that you wouldn't see any brighter image than you would in an 8x32 or 8x42 depending on if the day were summer sunny or winter cloudy. So most of the time, you're lugging around a heavier bin than you need. If the 8x56 SLC has less aberrations than the 8x42, and you want the purest image possible like Henry, then that's the reason to buy the 8x56 SLC, Or if you're a hunter and hunt in the winter when light levels are low and you're hunting near dusk.
Then there's the issue of weight. Have you worked as a grave digger?
It would also work well for stargazing under dark skies, although the 10x56 would work better for that if you could hold it steady.
An 8x42 EDG would be an all around more useful bin than the 8x56 SLC. It probably has more aberations than the 56 SLC (except chromatic aberration, which it controls well, it's also very good at controlling flare, which is probably true of the 7x42 as well).
If the compressed image caused by field flatteners doesn't bother you in the 7x42, it probably wouldn't in the 8x42 EDG, but if you have the 7x42, the 8x42 would be redundant since the view is nearly the same, though the apparent field of view in the 8x42 is wider, even more open than the simple formula would indicate due to the degree of pincushion.
Very open view and plenty bright despite some saying the 8x42 EDG's view is dark. That's just when comparing it to bins that are boosted in the middle of the light spectrum. It actually has better color rendition than most of the competition, which I prefer.
Anyway, it looks like you've already have a nice stable of binoculars. Get outside and enjoy them now that we're heading towards spring!
